[PATCH 4/9] drm/mediatek: add CONFIG_OF dependency

[Arnd Bergmann]

The mediatek DRM driver can be configured for compile testing with
CONFIG_OF disabled, but then fails to link:

drivers/gpu/built-in.o: In function `mtk_drm_bind':
analogix_dp_reg.c:(.text+0x52888): undefined reference to `of_find_device_by_node'
analogix_dp_reg.c:(.text+0x52930): undefined reference to `of_find_device_by_node'

This adds an explicit Kconfig dependency.

I originally sent this on May 18 when the driver was newly added,
but my fix never made it.
